Robust Model Predictive control of Cement Mill circuits

The present work considers the control of ball mill grinding circuits which are characterized by non-linearities and disturbances. The disturbances are due to large ariationsv and heterogeneities in the feed material. Thus the models obtained by simple tests on these mills are subject to large uncertainties which may result

Playing ball with the Haber–Bosch process - Advanced ...

In an eye-opening recent report it was demonstrated that the ammonia synthesis process could be powered mechanochemically in a simple ball mill laboratory experiment under the seemingly very gentle conditions of 45 °C and 1 atmosphere. The mechanochemical ammonia yield reported was found to be significantly higher than the Haber–Bosch.
